Just wondering if an Airtronics tx would work with a spectrum rx 2.4 or just in general what are some compatible set-ups?

Manufacturers use proprietary encoding systems which means they are not compatible with each other

Cheers

There are no general compatibilities with 2.4 systems.

Even the high priced systems and low priced systems within a brand (Futaba for example) are not compatible with each other.

thanks for your responses. just jumping back in after a 15 year absence and wasnt sure how it worked.
